1 kW, 2000 rpm, 5 Nm — the torque and speed that define the load match
The 1FL2306-2AC11-1SB0: Rated power is 1 kW at 2000 rpm on 400 V 3AC supply — this is the continuous-duty ceiling for thermal sizing. Holding torque M0 is 5 Nm; rated torque Mn is 4.78 Nm, so the motor holds the load at standstill without overheating and delivers nearly full torque continuously across the speed range. The 22-bit AS absolute encoder (single-turn or multi-turn depending on the S200 drive configuration) gives position feedback with 0.005° resolution per revolution — no homing cycle needed on power-up when paired with the matching SINAMICS S200 drive. Shaft height is 65 mm with a key and tolerance N (ISO fit), so the coupling bore and the motor pilot match standard NEMA/IEC metric flanges. The angular connector exits the motor axially or radially — plan cable routing before the motor is bolted down.
Product class C means this is manufactured to order and non-returnable — confirm the shaft key, connector orientation, and brake voltage on the PO before the factory cuts steel.
IP65 with oil seal — washdown-ready, but check the connector seal
Protection class IP65 with an oil seal means the motor body resists dust ingress and low-pressure water jets from any direction — suitable for coolant splash zones on machine tools, food processing lines, or packaging equipment where washdown is periodic, not continuous. The holding brake is integrated — 5 Nm holding torque matches the standstill torque rating, so no external brake resistor or mechanical latch is needed for vertical-axis loads that must hold position when the drive is disabled.
Compliance and export — RoHS, REACH, no ITAR restriction
RoHS compliant since 01-01-18; REACH Art. 33 candidate-list substances are declared via the standard Siemens Reach Information document. Export control classification is AL:N / ECCN:N — no ITAR or dual-use restriction, so cross-border shipment to most destinations is straightforward without an export license.
